McBride, 38, is widely considered one of the greatest forwards the United States has ever produced, having found success domestically, in Europe and on the international scene.

“Brian is one of the cornerstones of American soccer,” Fire technical director Frank Klopas said in a statement. “Since joining the Fire, and returning to Chicago, he has shown the characteristics that have made him a success on every level of soccer in this country."

A US national team veteran known for his fearsome aerial ability, McBride was the first US player to score in two World Cups. He tallied two game-winning goals in the 2002 edition and finished his international career, which spanned three World Cups, with 30 goals in 95 appearances.

Following a stint in Germany, McBride joined MLS as the league's first-ever draft pick in the inaugural season of 1996. He went on to net 62 goals for the Columbus Crew in 161 appearances before heading to England, where he enjoyed a successful career at Fulham.

After scoring 40 goals for the Cottagers over four campaigns, McBride left Fulham as team captain and club legend. The Chicago-area native returned to MLS and joined his hometown Fire in 2008. In all, he has appeared in 211 MLS games, scoring 78 goals and adding 51 assists over the course of his 11-year MLS career.

"He is a consummate professional and embodies everything that is good in the game," Klopas said. "His leadership, everlasting commitment and work ethic on the field are parallel to his impact off of it. We wish Brian and his family the best of luck as he takes this next step in life.”
